Miami signed free agent running back Knowshon Moreno to a one-year, $3 million deal back in March to come in and compete for the starting job with Lamar Miller and Daniel Thomas.

While the 26-year-old has worked with the starting group during OTAs and even lined up in the same backfield as Miller on occasion, it's safe to say he hasn't made a positive impression thus far.
